PHOTO INTERPRETATION PICTURE, COLWELL 
  
Figs. 11A (top) and 11B. Another example of the misinterpretation that can 
be made by those having inadequate appreciation of the geometry of aerial 
photos. Automobiles A and B are actually of about the same length despite 
their photo appearance, and the same is true for dump trucks C and D. Note 
in Fig. 11B that all vehicles on one half of the freeway are foreshortened and 
all those on the other half are elongated. For further explanation, see text.
